Many popular sights (often religious ones) have strict dress codes for visitors.
Then you could at least buy a cheap shirt or pair of pants from a local vendor.
If you plan to visit someplace with warm weather, carry a large scarf with you.
Dont assume that youll be able to talk your way past the dress code, either.
Every place Ive personally been to very strictly enforces it.
